I am unable load CSV files to an item page. My site uses the antimatter theme, and the assets plugin to call js files from the Item directory. In that same directory, I have save a csv file. When I attempt to load the csv data via javascript, I get a 404 error in the console output (appears to look for the file in the parent blog directory, rather than the item directory). How can I specify the the correct dir location in my js files?
